Hi viv;...my reply on pg 5 "simply the air we breathe
pg 14 " only function by the air we breathe", and.."all possible by the air we breathe "..
The part you highlighted was sandwiched in between, which was showing the effects of the spirit or air we breathe which gives rise to what many would call 'our spirit' which can also be known as 'our way' ,our personality, our demeanour, our attitude as in he's got a good spirit. Spirit in those senses being used as descriptive In the context of the context of the conversation ,
In that sense the word spirit is surely understandable.
your point about other creatures ? I am talking in the context of human spirit.
your point about force; there is no correlation between the force of a bullet or any other missiles impact and the force of the air we breathe.
it only serves as a distraction of the context.
Your point about the source of the oxygen ? Why would that have any relevance to the fact that we breathe it ?
Your point about gravity? Humans do not breathe gravity , I would not make any argument that gravity was spirit.....would you?...would anyone?
Best wishes
